Flow Control around the UAS-S45 Pitching Airfoil Using a Dynamically Morphing Leading Edge (DMLE): A Numerical Study

open access: yesBiomimetics, 2023
This paper investigates the effect of the Dynamically Morphing Leading Edge (DMLE) on the flow structure and the behavior of dynamic stall vortices around a pitching UAS-S45 airfoil with the objective of controlling the dynamic stall.

Context updates are hierarchical

open access: yesGlossa, 2016
This squib studies the order in which elements are added to the shared context of interlocutors in a conversation. It focuses on context updates within one hierarchical structure and argues that structurally higher elements are entered into the context ...

Explaining presupposition projection with dynamic semantics

open access: yesSemantics and Pragmatics, 2011
Heim's (1982, 1983b) dynamic semantics provides an attractive system for capturing the basic facts about presupposition projection. A long-standing criticism of this semantics is that it requires for each connective lexical stipulations that are not ...

δ-Almost Periodic Functions and Applications to Dynamic Equations

open access: yesMathematics, 2019
In this paper, by employing matched spaces for time scales, we introduce a δ -almost periodic function and obtain some related properties. Also the hull equation for homogeneous dynamic equation is introduced and results of the existence are ...

Dynamic Scene Semantics SLAM Based on Semantic Segmentation

open access: yesIEEE Access, 2020
Simultaneous Localization and Mapping (SLAM) have become a new research hotspot in the field of artificial intelligence applications such as unmanned driving and mobile robots. Most of the current SLAM research is based on the assumption of static scenes,

Dynamics and Elastic Properties of Glassy Metastable States

open access: yesSolids, 2021
By a molecular dynamics (MD) simulation method which ensures the system will be under hydrostatic pressure, dynamic and elastic properties of glassy metatstable states are investigated.

A trajectory-based strict semantics for program slicing

open access: yes, 2010
We define a program semantics that is preserved by dependence-based slicing algorithms. It is a natural extension, to non-terminating programs, of the semantics introduced by Weiser (which only considered terminating ones) and, as such, is an accurate ...

A symbolic semantics for a clculus for service-oriented computing

open access: yes, 2009
We introduce a symbolic characterisation of the operational semantics of COWS, a formal language for specifying and combining service-oriented applications, while modelling their dynamic behaviour.
